Product Details

Portable Coal Gas Analyzer KGD - MQ - 520 can be used to measure the volume concentration of gases.
Product Introduction
The Portable Coal Gas Analyzer KGD - MQ - 520 adopts non - dispersive infrared (NDIR) gas analysis technology with independent intellectual property rights, long - life electrochemical sensing technology, and MEMS - based thermal conductivity technology. It can simultaneously measure the calorific values of coal gas and biogas, as well as the volume concentrations of gases such as CO, CO₂, CH₄, H₂, O₂, and CₙHₘ.

Product Features

  • Simultaneously measures gas components and calorific values: It can simultaneously measure the volume concentrations of gases such as CO, CO₂, CH₄, H₂, O₂, and CₙHₘ, and automatically calculate and display the calorific values of coal gas and natural gas, replacing the combustion - type calorific value meter.
  • High measurement accuracy: No cross - interference among multi - component measured gases: CₙHₘ has no interference on the measurement result of CH₄, and CO, CO₂, and CH₄ have no interference on the measurement result of H₂. It is less affected by the outside world, and the change of gas sampling flow has no impact on the measurement result of the H₂ thermal conductivity sensor. Measuring the volume concentration of CₙHₘ ensures the accuracy of the calorific values of gases such as coke oven gas, mixed gas, producer gas, and straw gas.
  • Portable body design: Easy to carry, it can meet the needs of both on - site industrial measurement and laboratory airbag sampling analysis.
  • Intelligent power management: Soft - start power switch and intelligent battery power management avoid the instrument from operating under low - power conditions.
  • Simple data management: Automatically stores measurement data, with query and deletion functions, and can transmit data to the superior centralized control system through multiple interfaces.
  • Low cost of use: Compared with gas analysis technologies such as Orsat and chromatography, the measurement process does not require disassembly and installation, consumption of chemical reagents, etc. It has a simple structure, is easy to operate, and has no consumables.
